Possible disruption at Pex Hill -
We have been informed that the landowner plans to undertake significant work which may result
in large portions of the car-park being closed off. If you are planning on visiting the observatory,
please keep an eye on our Twitter account for updates (you don't need to have Twitter yourself to view it).
The latest information as of Friday 21st September is that the on-going work will continue into 2019 and will mean restricted access and parking. We intend to continue with the meetings on Wednesday evenings as long as it is safe to do so.
Anybody that visits MUST park safely and allow the access of emergency services at all times.

Most recent Western Europe RGB Airmass composite. Updated hourly.This is composed of two water-vapour channels, at 6.2µm and 7.3µm, and two infra-red channels at 9.7µm and 10.8µm.Low cloud does not stand out unless it of a significantly different temperature to the background (sea or land). High cloud stands out, and air-humidity can be discerned.In this composite, clear, dry air glows a yellow-ish green, while moist air has blue hues. This can be helpful in predicting the seeing conditions. The reason it’s possible for cloud to be in the same area as dry air is because we are looking at different layers (heights) of the atmosphere merged into one image.This image is Copyright 2013 EUMETSAT

Most recent UK RGB EVIEW composite. Updated hourly during daylight hours (not updated at night).This is composed of data from the from the SEVIRI high-resolution visible channel, and also the infra-red channel at 10.8µm.This combination of spectral channels gives a good idea of cloud cover and a fairly natural feel to the image.This image is Copyright 2013 EUMETSAT
